It's not really a matter of recommendation. All I mean is that the shorter your average trade lasts and the more trades you make per day, the more futures rather than SB makes sense.
more trades you make more commission you pay..SB no commission. Just the spread
The dependency is not on the frequency but the relative amount taken on each trade. You would need to make sure that all your high frequency (=high cost) DMA trades are actually being covered.
